Objective: The aim of this study was to investigate the prognostic value of baseline peripheral blood neutrophils, monocytes, and lymphocytes on locally advanced rectal cancer (LARC) patients.

Methods: Clinicopathologic data of 317 LARC patients during July 2010 and October 2016 were retrospectively gathered. X-tile software was used to acquire the optimal cutoff values of neutrophils, monocytes, and lymphocytes.

Article Synopsis
  • Toxoplasma gondii is a parasite that infects warm-blooded animals, with infected pigs being a major source of infection in humans, highlighting the need for effective diagnosis in swine.
  • A new PCR method targeting the GRA14 gene has been developed, which can detect T. gondii DNA during the acute infection phase with high specificity and sensitivity, even finding as few as 2.35 tachyzoites in various specimen types.
  • A study involving 5,462 blood samples from pigs in southern China revealed an 18.9% infection rate, with higher positive rates observed in specific regions and seasons, indicating the new PCR method's effectiveness for diagnosing swine toxoplasmosis in clinical settings.

Background: The National Comprehensive Cancer Network (NCCN) guidelines recommend examination of a minimum of 12 lymph nodes (LNs) for accurate staging of a single case of colorectal cancer. However, the guidelines do not support the examination of LNs in synchronous colorectal carcinoma (SCC). This study aimed to investigate the association between lymph node yield and the prognosis of SCC patients.

Background: Major resection (MR) is recommended for cases with T2 finding after local excision (LE) of early rectal cancer, but the revision procedure is accompanied with high morbidity. We evaluated the oncological safety of LE followed by adjuvant radiotherapy as a rectum-preserving alternative to MR for T2 early rectal cancer.

Methods: A total of 3786 patients with T2N0M0 rectal adenocarcinoma between 1998 and 2013 were included from the SEER database.

Radiation-induced intestinal fibrosis (RIF) is a chronic toxicity following radiation, and can be very difficult to treat. Pirfenidone is a promising anti-fibrotic agent that inhibits fibrosis progression in various clinical and experimental studies. This study was aimed to explore whether pirfenidone could protect against RIF, and to evaluate the underlying mechanism.

Background: Early postoperative small bowel obstruction (EPSBO) is a common complication following colon cancer surgery. EPSBO is associated with increased hospital stays, mortality rates, and healthcare costs. The purpose of this study was to identify risk factors for EPSBO following elective colon cancer surgery.

To compare the surgical and oncological outcomes of rectal mucinous adenocarcinomas treated with neoadjuvant chemoradiotherapy versus surgery alone. A total of 167 locally advanced rectal mucinous adenocarcinoma patients treated with neoadjuvant chemoradiotherapy and surgery alone between 2008 and 2014 were matched using propensity score; the surgical and oncological outcomes were compared. Ninety-six patients were matched.

Local excision is an alternative to radical surgery that is indicated in patients with locally advanced rectal cancer (LARC) who have a good response to chemoradiotherapy (CRT). Regional lymph node status is a major uncertainty during local excision of LARC following CRT. We retrospectively reviewed clinicopathologic variables for 244 patients with LARC who were treated at our institute between December 2000 and December 2013 in order to identify independent predictors of regional lymph node metastasis.

Background: Traditionally, conventional intersphincteric resection requires a combined abdominal and perineal approach and a handsewn coloanal anastomosis procedure, which is difficult to accomplish via the perineal approach. A completely abdominal approach partial intersphincteric resection (APISR) with laparoscopy can simplify the anastomosis procedure. This study evaluated the intermediate-term oncological and functional results of laparoscopic versus open APISR for low rectal cancer.

Article Synopsis
  • This study aims to create a prediction scoring system to identify lymph node metastasis in the inferior mesenteric artery (IMA) for patients with stage III rectal cancer and evaluate the effect of removing positive IMA nodes on their prognosis.
  • The researchers analyzed data from 264 patients who underwent surgery and found significant indicators of IMA node metastasis, leading to the development of a scoring system that demonstrated reasonable sensitivity and specificity.
  • The results revealed that patients with positive IMA nodes had much lower 5-year survival rates compared to those with negative nodes, confirming that IMA lymph node metastasis is a significant negative prognostic factor for stage III rectal cancer.

Objective: To investigate the incidence, risk factors and preventative methods associated with chyle leak following complete mesocolic excision(CME) for colon cancer.

Methods: Clinical data of 592 patients with colon cancer undergoing CME in the department of Colorectal Surgery in the Fujian Medical University Union Hospital from September 2000 to September 2011 were analyzed retrospectively.

Results: Chyle leak occurred in 46 patients(7.

Article Synopsis
  • The study aimed to compare long-term outcomes of laparoscopic versus open complete mesocolic excision (CME) for colon cancer in 273 patients.
  • No significant differences were found in margin lengths, lymph node counts, or recurrence/metastasis rates between the laparoscopic and open surgery groups after an average follow-up of 50 months.
  • The overall and disease-free survival rates were similar between the two surgical approaches, suggesting that laparoscopic CME could be a standardized option for colon cancer treatment.
